How to calculate cooling capacity per square foot

This calculator finds cooling capacity per square foot by dividing total cooling capacity by the conditioned floor area — useful for sanity-checking whether a system is appropriately sized for a space.

How the calculation works

Capacity per sq ft = Total cooling capacity (BTU) ÷ Floor area (sq ft).

Example

A 24,000 BTU system cooling a 1,000 sq ft space: Capacity per sq ft = 24,000 ÷ 1,000 = 24 BTU/sq ft.
